CASPER FAUST, OF RHINELANDER, WISCONSIN.

LOCK.

SPECIFICATION formingpart of Letters Patent N0. 752,148, dated February 16, 1904.

Application filed May 25, 1903. Serial No. 158,717. (No model.)

To all whom it may concern:

Be it known that I, CASPER FAUs'r, a citizen of the United States, residing at Rhinelander, in the county of Oneida and State of Wisconsin, have invented certain new and useful Improvements in Locks; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to looks, and more particularly to that class of locks wherein guards or tumblers are employed requiring the use of a key whose bit is adapted to retract the tumblers in order to operate'the lock and in which the bolt is held in'its locked and unlocked position by engagement with the tumblers.

The object of the invention is to provide an improved lock of this character wherein the parts are operated without the use of springs and positive movement is imparted to the bolt in both directions by the direct action of the key thereon, thus simplifying the construction and dispensing with the use of parts which are liable to get out of order.

With this and other objects in view the invention consists in certain novel features of construction, combination, and arrangement of parts, as will be hereinafter more fully described, and particularly pointed out in the appended claim, reference being had to the accompanying drawings, in which Figure 1 is a plan view of the lock with the 3 5 face-plate removed and showing the latchbolt projected and the locking-bolt retracted. Fig. 2 is a section of the same on line 2 2 of Fig. 1, and Fig. 3 is a perspective view of one of the wards.

Referring to the drawings, the numeral 1 designates the casing of the lock, which may be of any approved construction and in which is mounted a latch-bolt 2,- having at its inner end a yoke 3, through which projects a knob- 4 5 shaft 4. The shaft t carries a tumbler 5, having oppositely-projecting arms 6 and 7 which are adapted to engage right-angular projections 6 and 7 at the free ends of the arms of the yoke 3, by means of which the said bolt 2 5 may be projected and retracted. The form of the arm 10, projecting from the upper or rear corner of a substantially rectangular gravityretracting weight 11. This weight 11 is also provided with a rearwardly-extending arm 12,

which is fulcrumed upon a cross piece or pin- 0 l3, suitably formed or provided upon the easing 1. The weight 11 is thus so mounted that when the latch 2 is retracted by a proper manipulation of the tumbler 5 the pin 8 will work within the slot 9 and tilt the said weight 5 upwardly and rearwardly on the pin 13, whereby when the knob is-released theweight will drop back to its normal position and automatically project the bolt. Anight-latch detent or lever 14 lies above the shank of the 7 bolt 2 and is pivoted at its inner end upon a pin 15 to move toward and from said shank. In its lower edge'this detent or lever is formed with a notch 16 to cooperate with the bit of a night latch key 17, which latter is permanentl'y fastened to the door by means of an escutcheon'or other suitable-form ,of fastening. (Not shown.) When the bit of the key 17 is turned upwardly, the detentld: will be moved away from the bolt 2, thus allowing the latter to be operated; but when the key is turned in the reverse direction the said detent will drop down behind the shoulder at the inner end of the head of said bolt, -and I thus lock the bolt against inward movement 5 or retraction.

Disposed below the latch mechanismabove described is a sliding locking-bolt 18, which is guided by a pin 19, fixed to the casing and projecting through a slot 20 in the bolt. This 9 bolt is provided in rear of the slot with a pin 21, and the casing is provided above the bolt with a pin 22. A third pin 23 is fixed to the casing below the bolt and cooperates with the pin 19 to guide the bolt in its movement. The pin 23 also serves as a stop to lock the bolt in its projected and retracted positions. A keylever or tumbler 2a is provided at its end with slots 25 and 26, receiving the pins 21 and 22, by means of which it is given a pivotal slip- I joint connection with the bolt at its lower end and a sliding slip-joint connection with the casing at its upper end, thus being retained in position by said pins and guided longitudinally in a substantially vertical plane. The said key-lever is also provided with akeyhole-slot 27 to receive the key 28, which is inserted from engagement with the pin 23, leaving the bolt 18 free to. be projected. Hence it will be seen that a partial movement in one direction by the key 28 will lift the key-lever and release the bolt and that a continuation of such movement will slide the bolt 18 outward until fully projected, when upon the withdrawal of the key 28 the key-lever will again drop down, with its forward end in advance of the key 28, so that the latter will act as a stop to hold the bolt 18 frombeing retracted. Thus the pin 23 and the key-lever cooperate to lock the bolt in either of its positions.

The web 29 of the key 28 is provided with one or more notches or recesses 30. Secured to the casing are wards 31, corresponding in number to the notches 30 in the key, each of said wards having a beveled segmental surface 32, designed to fit a notch in the key to allow the latter to be turned and to prevent turning of the key should the latter be unprovided with the proper number or form of notches. Any number of these wards may be employed to adapt the lock for operation by keys whose bits are formed with differentlyshaped notches and different numbers of notches.

From the foregoing description, taken in connection with the accompanying drawings, the construction and mode of operation of my invention will be readily understood. It will be seen that it provides a simple and effective lock in which the parts are adapted to operate without the use of springs, which will be liable to get out of order and increase the expense of construction.

Various changes in the form, proportion, and the minor details of construction may be resorted to without departing from the principle or sacrificing any of the advantages of the invention.

Having thus described my invention,'what I claim as new, and desire to secure by Letters Patent, is

In a lock, the combination with a casing, of

a sliding bolt, a key-lever having a pivotalslipjoint connection at one end with the bolt and a sliding slip-joint connection at its opposite end with the casing, said bolt being thus mounted to swing and to slide or reciprocate at an angle to the bolt, and provided between said connections with a key-engaging portion, and a stop device coacting with the bolt-connecting-end of the lever, the latter being adapted to move in front or in rear of said stop device when retracted to lock the bolt in projected or retracted position.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.

CASPER FAUST.
